Jadassohn, Salomon, German pedagogue, conductor, and composer; b. Breslau, Aug. 13, 1831; d. Leipzig, Feb. 1, 1902. He studied with Brosig, Hesse, and Lüstner in Breslau, at the Leipzig Cons. (1848–49), and with Liszt in Weimar. He then studied with Hauptmann in Leipzig, where he settled. He founded a choral society, Psalterion (1866), and conducted the concerts of the Euterpe Soc. (1867–69). In 1871 he was appointed instructor at the Leipzig Cons., being made Ph.D. (honoris causa, 1887) and Royal Prof. (1893). A scholar of the highest integrity and of great industry, he codified the traditional views of harmony, counterpoint, and form in his celebrated manuals. He was a firm believer in the immutability of harmonic laws, and became the Rock of Gibraltar of conservatism in musical teaching. Through his many students, who in turn became influential teachers in Germany and other European countries, the cause of orthodox music theory was propagated far and wide. He composed four syms., two piano concertos, chamber music, choral works, piano pieces, and songs. Although he was a master of contrapuntal forms, his music is totally forgotten.
